It is usually expected that crops treated with a plant growth regulatorshow the same or even increased phytotoxic damages when exposed to apesticide compared to the untreated crop. Surprisingly, it has now beenfound that the application of a compound of the formula I and a plantgrowth regulator to the crops can reduce these phytotoxic damages of thecrops significantly.

In the compounds of the formula I, each alkyl moiety either alone or aspart of a larger group is a straight or branched chain and is, forexample, methyl, ethyl, n-propyl, n-butyl, iso-propyl, sec-butyl,iso-butyl, tert-butyl, n-pentyl, iso-pentyl and n-hexyl.

Alkoxy groups preferably have a preferred chain length of from 1 to 4carbon atoms. Alkoxy is, for example, methoxy, ethoxy, propoxy,i-propoxy, n-butoxy, isobutoxy, sec-butoxy and tert-butoxy. Such groupscan be part of a larger group such as alkoxyalkyl and alkoxyalkoxyalkyl.Alkoxyalkyl groups preferably have a chain length of 1 to 4 carbonatoms. Alkoxyalkyl is, for example, methoxymethyl, methoxyethyl,ethoxymethyl, ethoxyethyl, n-propoxymethyl, n-propoxyethyl orisopropoxymethyl.

Halogen is generally fluorine, chlorine, bromine or iodine. This alsoapplies, correspondingly, to halogen in combination with other meanings,such as haloalkyl.

Haloalkyl groups preferably have a chain length of from 1 to 6 carbonatoms. Haloalkyl is, for example, fluoromethyl, difluoromethyl,trifluoromethyl, chloromethyl, dichloromethyl, trichloromethyl,2,2,2-trifluoroethyl, 2-fluoroethyl, 2-chloroethyl, pentafluoroethyl,1,1-difluoro-2,2,2-trichloroethyl, 2,2,3,3-tetrafluoroethyl and2,2,2-trichloroethyl; preferably trichloromethyl, difluorochloromethyl,difluoromethyl, trifluoromethyl and dichlorofluoromethyl.

The cycloalkyl groups preferably have from 3 to 6 ring carbon atoms, forexample cyclopropyl, cyclobutyl, cyclopentyl and cyclohexyl. In theserings, a methylene group can be replaced by an oxygen and/or sulphuratom, which leads, for example, to oxetanyl, tetrahydrofuranyl,tetrahydropyranyl, furanyl, tetrahydro-thiofuranyl andtetrahydro-thiopyranyl rings.

Phenyl, also as part of a substituent such as benzyl, may besubstituted, preferably by alkyl, haloalkyl or halogen groups. In thiscase, the substituents can be in ortho, meta and/or para position. Thepreferred substituent positions are the ortho and para positions to thering attachment point.

The latentiating groups G are selected to allow its removal by one or acombination of biochemical, chemical or physical processes to affordcompounds of formula I where G is hydrogen before, during or followingapplication to the treated area or plants. Examples of these processesinclude enzymatic cleavage, chemical hydrolysis and photoloysis.Compounds bearing such groups G may offer certain advantages, such asimproved penetration of the cuticula of the plants treated, increasedtolerance of crops, improved compatibility or stability in formulatedmixtures containing other herbicides, herbicide safeners, plant growthregulators, fungicides or insecticides, or reduced leaching in soils.

It is preferred that G is hydrogen, a metal, preferably an alkali metalor alkaline earth metal, or an ammonium or sulfonium group, wherehydrogen is especially preferred.

Depending on the nature of the substituents, compounds of formula I mayexist in different isomeric forms. When G is hydrogen, for example,compounds of formula I may exist in different tautomeric forms:

This invention covers all isomers and tautomers and mixtures thereof inall proportions. Also, when substituents contain double bonds, cis- andtrans-isomers can exist. These isomers, too, are within the scope of theclaimed compounds of the formula I.

The invention covers also to the agriculturally acceptable salts whichthe compounds of formula I are able to form with transition metal,alkali metal and alkaline earth metal bases, amines, quaternary ammoniumbases or tertiary sulfonium bases.

Among the transition metal, alkali metal and alkaline earth metal saltformers, special mention should be made of the hydroxides of copper,iron, lithium, sodium, potassium, magnesium and calcium, and preferablythe hydroxides, bicarbonates and carbonates of sodium and potassium.

Pure diastereomers or enantiomers can be obtained according to theinvention not only by separating suitable isomer mixtures, but also bygenerally known methods of diastereoselective or enantioselectivesynthesis, for example by carrying out the process according to theinvention with starting materials of a suitable stereochemistry.

It is advantageous to isolate or synthesize in each case thebiologically more effective isomer, for example enantiomer ordiastereomer, or isomer mixture, for example enantiomer mixture ordiastereomer mixture, if the individual components have a differentbiological activity.

The compounds I and, where appropriate, the tautomers thereof, in eachcase in free form or in salt form, can, if appropriate, also be obtainedin the form of hydrates and/or include other solvents, for example thosewhich may have been used for the crystallization of compounds which arepresent in solid form.

Preferably the crop plants are selected fromthe group consisting of corn, wheat, rice, soybean and also ornamentals.

The compositions according to the invention are preferably applied tomonocotylendonous crops. The term “crops” is to be understood asincluding also crops that have been rendered tolerant to herbicides likebromoxynil or classes of herbicides (such as, for example, HPPDinhibitors like isoxazoles like isoxaflutole and isoxachlortol, andtriones like mesotrione and sulcotrione, ALS inhibitors, for examplesulfonylurea like primisulfuron, prosulfuron, trifloxysulfuron,imidazolinones, triazolopyrimidines, phthalides andpyrimidyloxybenzoates, ACCase inhibitors such asaryloxyphenoxyalkanecarboxylic acids and cyclohexadiones, PROTOXinhibitors such as diphenyl ether, cyclic imides, phenyl pyrazoles,pyridines and oxadiazoles, EPSPS(5-enol-pyrovyl-shikimate-3-phosphate-synthase) inhibitors, GS(glutamine synthetase) inhibitors), as well as inhibitors ofphosphinothricin acetyltransferase, O-methyl transferase,adenylosuccinate lyase and synthase, anthranilate synthase, nitrilase,glyphosate oxidoreductase as described in Tables 1 to 3 ofUS2010/0130561.

An example of a crop that has been rendered tolerant to imidazolinones,e.g. imazamox, by conventional methods of breeding (mutagenesis) isClearfield® summer rape (Canola). Examples of crops that have beenrendered tolerant to herbicides or classes of herbicides by geneticengineering methods include glyphosate- and glufosinate-resistant maizevarieties commercially available under the trade names RoundupReady® andLibertyLink®.

The term “crops” is to be understood as including also crop plants whichhave been so transformed by the use of recombinant DNA techniques thatthey are capable of synthesising one or more selectively acting toxins,such as are known, for example, from toxin-producing bacteria,especially those of the genus Bacillus.

Toxins that can be expressed by such transgenic plants include, forexample, insecticidal proteins from Bacillus cereus or Bacilluspopilliae; or insecticidal proteins from Bacillus thuringiensis, such asδ-endotoxins, e.g. Cry1Ab, Cry1Ac, Cry1F, Cry1Fa2, Cry2Ab, Cry3A,Cry3Bb1 or Cry9C, or vegetative insecticidal proteins (Vip), e.g. Vip1,Vip2, Vip3 or Vip3A; or insecticidal proteins of bacteria colonisingnematodes, for example Photorhabdus spp. or Xenorhabdus spp., such asPhotorhabdus luminescens, Xenorhabdus nematophilus; toxins produced byanimals, such as scorpion toxins, arachnid toxins, wasp toxins and otherinsect-specific neurotoxins; toxins produced by fungi, such asStreptomycetes toxins, plant lectins, such as pea lectins, barleylectins or snowdrop lectins; agglutinins; proteinase inhibitors, such astrypsin inhibitors, serine protease inhibitors, patatin, cystatin,papain inhibitors; ribosome-inactivating proteins (RIP), such as ricin,maize-RIP, abrin, luffin, saporin or bryodin; steroid metabolismenzymes, such as 3-hydroxysteroidoxidase,ecdysteroid-UDP-glycosyl-transferase, cholesterol oxidases, ecdysoneinhibitors, HMG-COA-reductase, ion channel blockers, such as blockers ofsodium or calcium channels, juvenile hormone esterase, diuretic hormonereceptors, stilbene synthase, bibenzyl synthase, chitinases andglucanases.

In the context of the present invention there are to be understood byδ-endotoxins, for example Cry1Ab, Cry1Ac, Cry1F, Cry1Fa2, Cry2Ab, Cry3A,Cry3Bb1 or Cry9C, or vegetative insecticidal proteins (Vip), for exampleVip1, Vip2, Vip3 or Vip3A, expressly also hybrid toxins, truncatedtoxins and modified toxins. Hybrid toxins are produced recombinantly bya new combination of different domains of those proteins (see, forexample, WO 02/15701). Truncated toxins, for example a truncated Cry1Ab,are known. In the case of modified toxins, one or more amino acids ofthe naturally occurring toxin are replaced. In such amino acidreplacements, preferably non-naturally present protease recognitionsequences are inserted into the toxin, such as, for example, in the caseof Cry3A055, a cathepsin-G-recognition sequence is inserted into a Cry3Atoxin (see WO 03/018810).

Examples of such toxins or transgenic plants capable of synthesisingsuch toxins are disclosed, for example, in EP-A-0 374 753, WO 93/07278,WO 95/34656, EP-A-0 427 529, EP-A-451 878 and WO 03/052073.

The processes for the preparation of such transgenic plants aregenerally known to the person skilled in the art and are described, forexample, in the publications mentioned above. Cry1-type deoxyribonucleicacids and their preparation are known, for example, from WO 95/34656,EP-A-0 367 474, EP-A-0 401 979 and WO 90/13651.

The toxin contained in the transgenic plants imparts to the plantstolerance to harmful insects. Such insects can occur in any taxonomicgroup of insects, but are especially commonly found in the beetles(Coleoptera), two-winged insects (Diptera) and moths (Lepidoptera).

Transgenic plants containing one or more genes that code for aninsecticidal resistance and express one or more toxins are known andsome of them are commercially available. Examples of such plants are:YieldGard® (maize variety that expresses a Cry1Ab toxin); YieldGardRootworm® (maize variety that expresses a Cry3Bb1 toxin); YieldGardPlus® (maize variety that expresses a Cry1Ab and a Cry3Bb1 toxin);Starlink® (maize variety that expresses a Cry9C toxin); Herculex I®(maize variety that expresses a Cry1 Fa2 toxin and the enzymephosphinothricine N-acetyltransferase (PAT) to achieve tolerance to theherbicide glufosinate ammonium); NuCOTN 33B® (cotton variety thatexpresses a Cry1Ac toxin); Bollgard I® (cotton variety that expresses aCry1Ac toxin); Bollgard HO (cotton variety that expresses a Cry1Ac and aCry2Ab toxin); VipCot® (cotton variety that expresses a Vip3A and aCry1Ab toxin); NewLeaf® (potato variety that expresses a Cry3A toxin);NatureGard®, Agrisure® GT Advantage (GA21 glyphosate-tolerant trait),Agrisure® CB Advantage (Bt11 corn borer (CB) trait) and Protecta®.

The active ingredients according to the invention can be used forcontrolling, i.e. containing or destroying, pests of the abovementionedtype which occur in particular on plants, especially on useful plantsand ornamentals in agriculture, in horticulture and in forests, or onorgans, such as fruits, flowers, foliage, stalks, tubers or roots, ofsuch plants, and in some cases even plant organs which are formed at alater point in time remain protected against these pests.

Suitable target crops are, in particular, cereals, such as wheat,barley, rye, oats, rice, maize or sorghum; beet, such as sugar or fodderbeet; fruit, for example pomaceous fruit, stone fruit or soft fruit,such as apples, pears, plums, peaches, almonds, cherries or berries, forexample strawberries, raspberries or blackberries; leguminous crops,such as beans, lentils, peas or soya; oil crops, such as oilseed rape,mustard, poppies, olives, sunflowers, coconut, castor, cocoa or groundnuts; cucurbits, such as pumpkins, cucumbers or melons; fibre plants,such as cotton, flax, hemp or jute; citrus fruit, such as oranges,lemons, grapefruit or tangerines; vegetables, such as spinach, lettuce,asparagus, cabbages, carrots, onions, tomatoes, potatoes or bellpeppers; Lauraceae, such as avocado, Cinnamonium or camphor; and alsotobacco, nuts, coffee, eggplants, sugarcane, tea, pepper, grapevines,hops, the plantain family, latex plants and ornamentals.

Depending on the plant species or plant varieties, their location andgrowth conditions (soils, climate, vegetation period, diet), thetreatment according to the invention may also result in superadditiveeffects. Thus, for example, reduced application rates and/or widening ofthe activity spectrum and/or an increase in the activity of thecompositions according to the invention and compositions which lead tobetter plant growth, increased tolerance to high or lower temperatures,increased tolerance to drought or to water or soil salt content,increased flowering performance, easier harvesting acceleratedmaturation, higher harvest yields, better quality and/or highernutritional value of the harvested products, better storage abilityand/or processability of the harvested products are possible whichexceed the effects which were actually to be expected.

The compounds of formula I and plant growth regulators are generallyapplied as compositions such as emulsifiable concentrates, suspensionconcentrates, directly sprayable or dilutable solutions, spreadablepastes, dilute emulsions, soluble powders, dispersible powders, wettablepowders, dusts, granules or encapsulations in polymeric substances,which comprise—at least—one of the active ingredients according to theinvention and which are to be selected to suit the intended aims and theprevailing circumstances.

In these compositions, the active ingredient is employed in pure form, asolid active ingredient for example in a specific particle size, or,preferably, together with—at least—one of the auxiliaries conventionallyused in the art of formulation, such as extenders, for example solventsor solid carriers, or such as surface-active compounds (surfactants).

Examples of suitable solvents are: unhydrogenated or partiallyhydrogenated aromatic hydrocarbons, preferably the fractions C8 to C12of alkylbenzenes, such as xylene mixtures, alkylated naphthalenes ortetrahydronaphthalene, aliphatic or cycloaliphatic hydrocarbons, such asparaffins or cyclohexane, alcohols such as ethanol, propanol or butanol,glycols and their ethers and esters such as propylene glycol,dipropylene glycol ether, ethylene glycol or ethylene glycol monomethylether or ethylene glycol monoethyl ether, ketones, such ascyclohexanone, isophorone or diacetone alcohol, strongly polar solvents,such as N-methylpyrrolid-2-one, dimethyl sulfoxide orN,N-dimethylformamide, water, unepoxidized or epoxidized vegetable oils,such as unexpodized or epoxidized rapeseed, castor, coconut or soya oil,and silicone oils.

Solid carriers which are used for example for dusts and dispersiblepowders are, as a rule, ground natural minerals such as calcite, talc,kaolin, montmorillonite or attapulgite. To improve the physicalproperties, it is also possible to add highly disperse silicas or highlydisperse absorbtive polymers. Suitable particulate adsorptive carriersfor granules are porous types, such as pumice, brick grit, sepiolite orbentonite, and suitable non-sorptive carrier materials are calcite orsand. In addition, a large number of granulated materials of inorganicor organic nature can be used, in particular dolomite or comminutedplant residues.

Suitable surface-active compounds are, depending on the type of theactive ingredient to be formulated, non-ionic, cationic and/or anionicsurfactants or surfactant mixtures which have good emulsifying,dispersing and wetting properties. The surfactants mentioned below areonly to be considered as examples; a large number of further surfactantswhich are conventionally used in the art of formulation and suitableaccording to the invention are described in the relevant literature.

Suitable non-ionic surfactants are, especially, polyglycol etherderivatives of aliphatic or cycloaliphatic alcohols, of saturated orunsaturated fatty acids or of alkyl phenols which may containapproximately 3 to approximately 30 glycol ether groups andapproximately 8 to approximately 20 carbon atoms in the (cyclo)aliphatichydrocarbon radical or approximately 6 to approximately 18 carbon atomsin the alkyl moiety of the alkyl phenols. Also suitable arewater-soluble polyethylene oxide adducts with polypropylene glycol,ethylenediaminopo

dypropylene glycol or alkyl polypropylene glycol having 1 toapproximately 10 carbon atoms in the alkyl chain and approximately 20 toapproximately 250 ethylene glycol ether groups and approximately 10 toapproximately 100 propylene glycol ether groups. Normally, theabovementioned compounds contain 1 to approximately 5 ethylene glycolunits per propy

lene glycol unit. Examples which may be mentioned arenonylphenoxypolyethoxyethanol, castor oil polyglycol ether,polypropylene glycol/polyethylene oxide adducts, tributylpheno

xypolyethoxyethanol, polyethylene glycol oroctylphenoxypolyethoxyethanol. Also suitable are fatty acid esters ofpolyoxyethylene sorbitan, such as polyoxyethylene sorbitan trioleate.

The cationic surfactants are, especially, quarternary ammonium saltswhich generally have at least one alkyl radical of approximately 8 toapproximately 22 C atoms as substituents and as further substituents(unhalogenated or halogenated) lower alkyl or hydroxyalkyl or benzylradicals. The salts are preferably in the form of halides,methylsulfates or ethylsulfates. Examples are stearyltrimethylammoniumchloride and benzylbis(2-chloroethyl)ethyhammonium bromide.

Examples of suitable anionic surfactants are water-soluble soaps orwater-soluble synthetic surface-active compounds. Examples of suitablesoaps are the alkali, alkaline earth or (unsubstituted or substituted)ammonium salts of fatty acids having approximately 10 to approximately22 C atoms, such as the sodium or potassium salts of oleic or stearicacid, or of natural fatty acid mixtures which are obtainable for examplefrom coconut or tall oil; mention must also be made of the fatty acidmethyl taurates. However, synthetic surfactants are used morefrequently, in particular fatty sulfonates, fatty sulfates, sulfonatedbenzimidazole derivatives or alkylaryl sulfonates. As a rule, the fattysulfonates and fatty sulfates are present as alkali, alkaline earth or(substituted or unsubstituted) ammonium salts and they generally have analkyl radical of approximately 8 to approximately 22 C atoms, alkyl alsoto be understood as including the alkyl moiety of acyl radicals;examples which may be mentioned are the sodium or calcium salts oflignosulfonic acid, of the dodecylsulfuric ester or of a fatty alcoholsulfate mixture prepared from natural fatty acids. This group alsoincludes the salts of the sulfuric esters and sulfonic acids of fattyalcohol/ethylene oxide adducts. The sulfonated benzimidazole derivativespreferably contain 2 sulfonyl groups and a fatty acid radical ofapproximately 8 to approximately 22 C atoms. Examples ofalkylarylsulfonates are the sodium, calcium or triethanolammonium saltsof decylbenzenesulfonic acid, of dibutylnaphthalenesulfonic acid or of anaphthalenesulfonic acid/formaldehyde condensate. Also possible are,furthermore, suitable phosphates, such as salts of the phosphoric esterof a p-nonylphenol/(4-14)ethylene oxide adduct, or phospholipids.Further suitable phosphates are tris-esters of phosphoric acid withaliphatic or aromatic alcohols and/or bis-esters of alkyl phosphonicacids with aliphatic or aromatic alcohols, which are a high performanceoil-type adjuvant. These tris-esters have been described, for example,in WO0147356, WO0056146, EP-A-0579052 or EP-A-1018299 or arecommercially available under their chemical name. Preferred tris-estersof phosphoric acid for use in the new compositions aretris-(2-ethylhexyl) phosphate, tris-n-octyl phosphate andtris-butoxyethyl phosphate, where tris-(2-ethylhexyl) phosphate is mostpreferred. Suitable bis-ester of alkyl phosphonic acids arebis-(2-ethylhexyl)-(2-ethylhexyl)-phosphonate,bis-(2-ethylhexyl)-(n-octyl)-phosphonate, dibutyl-butyl phosphonate andbis(2-ethylhexyl)-tripropylene-phosphonate, wherebis-(2-ethylhexyl)-(n-octyl)-phosphonate is particularly preferred.

The compositions according to the invention can preferably additionallyinclude an additive comprising an oil of vegetable or animal origin, amineral oil, alkyl esters of such oils or mixtures of such oils and oilderivatives. The amount of oil additive used in the compositionaccording to the invention is generally from 0.01 to 10%, based on thespray mixture. For example, the oil additive can be added to the spraytank in the desired concentration after the spray mixture has beenprepared. Preferred oil additives comprise mineral oils or an oil ofvegetable origin, for example rapeseed oil such as ADIGOR® and MERO®,olive oil or sunflower oil, emulsified vegetable oil, such as AMIGO®(Rhône-Poulenc Canada Inc.), alkyl esters of oils of vegetable origin,for example the methyl derivatives, or an oil of animal origin, such asfish oil or beef tallow. A preferred additive contains, for example, asactive components essentially 80% by weight alkyl esters of fish oilsand 15% by weight methylated rapeseed oil, and also 5% by weight ofcustomary emulsifiers and pH modifiers. Especially preferred oiladditives comprise alkyl esters of C₈-C₂₂ fatty acids, especially themethyl derivatives of C₁₂-C₁₈ fatty acids, for example the methyl estersof lauric acid, palmitic acid and oleic acid, being important. Thoseesters are known as methyl laurate (CAS-111-82-0), methyl palmitate(CAS-112-39-0) and methyl oleate (CAS-112-62-9). A preferred fatty acidmethyl ester derivative is Emery® 2230 and 2231 (Cognis GmbH). Those andother oil derivatives are also known from the Compendium of HerbicideAdjuvants, 5th Edition, Southern Illinois University, 2000. Also,alkoxylated fatty acids can be used as additives in the inventivecompositions as well as polymethylsiloxane based additives, which havebeen described in WO08/037,373.

The application and action of the oil additives can be further improvedby combining them with surface-active substances, such as non-ionic,anionic or cationic surfactants. Examples of suitable anionic, non-ionicand cationic surfactants are listed on pages 7 and 8 of WO 97/34485.Preferred surface-active substances are anionic surfactants of thedodecyl-benzylsulfonate type, especially the calcium salts thereof, andalso non-ionic surfactants of the fatty alcohol ethoxylate type. Specialpreference is given to ethoxylated C₁₂-C₂₂ fatty alcohols having adegree of ethoxylation of from 5 to 40. Examples of commerciallyavailable surfactants are the Genapol types (Clariant AG). Alsopreferred are silicone surfactants, especially polyalkyl-oxide-modifiedheptamethyltrisiloxanes, which are commercially available e.g. as SilwetL-77®, and also perfluorinated surfactants. The concentration ofsurface-active substances in relation to the total additive is generallyfrom 1 to 30% by weight. Examples of oil additives that consist ofmixtures of oils or mineral oils or derivatives thereof with surfactantsare Edenor ME SU®, Turbocharge® (Syngenta AG, CH) and Actipron® (BP OilUK Limited, GB).

The said surface-active substances may also be used in the formulationsalone, that is to say without oil additives.

Furthermore, the addition of an organic solvent to the oiladditive/surfactant mixture can contribute to a further enhancement ofaction. Suitable solvents are, for example, Solvesso® (ESSO) andAromatic Solvent® (Exxon Corporation). The concentration of suchsolvents can be from 10 to 80% by weight of the total weight. Such oiladditives, which may be in admixture with solvents, are described, forexample, in U.S. Pat. No. 4,834,908. A commercially available oiladditive disclosed therein is known by the name MERGE® (BASFCorporation). A further oil additive that is preferred according to theinvention is SCORE® (Syngenta Crop Protection Canada.)

In addition to the oil additives listed above, in order to enhance theactivity of the compositions according to the invention it is alsopossible for formulations of alkylpyrrolidones, (e.g. Agrimax®) to beadded to the spray mixture. Formulations of synthetic latices, such as,for example, polyacrylamide, polyvinyl compounds or poly-1-p-menthene(e.g. Bond®, Courier® or Emerald®) can also be used. Solutions thatcontain propionic acid, for example Eurogkem Pen-e-trate®, can also bemixed into the spray mixture as activity-enhancing agents.

As a rule, the compositions comprise 0.1 to 99%, especially 0.1 to 95%,of active ingredient of thre formula land 1 to 99.9%, especially 5 to99.9%, of at least one solid or liquid adjuvant, it being possible as arule for 0 to 25%, especially 0.1 to 20%, of the composition to besurfactants (% in each case meaning percent by weight). Whereasconcentrated compositions tend to be preferred for commercial goods, theend consumer as a rule uses dilute compositions which have substantiallylower concentrations of active ingredient.

The compositions can also comprise further solid or liquid auxiliaries,such as stabilizers, for example unepoxidized or epoxidized vegetableoils (for example epoxidized coconut oil, rapeseed oil or soya oil),antifoams, for example silicone oil, preservatives, viscosityregulators, binders and/or tackifiers; fertilizers, in particularnitrogen containing fertilizers such as ammonium nitrates and urea asdescribed in WO08/017,388, which can enhance the efficacy of theinventive compounds; or other active ingredients for achieving specificeffects, for example ammonium or phosphonium salts, in particularhalides, (hydrogen)sulphates, nitrates, (hydrogen)carbonates, citrates,tartrates, formiates and acetates, as described in WO07/068,427 andWO07/068,428, which also can enhance the efficacy of the inventivecompounds and which can be used in combination with penetrationenhancers such as alkoxalated fatty acids; bactericides, fungicides,nematocides, plant activators, molluscicides or herbicides.

The compositions according to the invention are prepared in a mannerknown per se, in the absence of auxiliaries for example by grinding,screening and/or compressing a solid active ingredient and in thepresence of at least one auxiliary for example by intimately mixingand/or grinding the active ingredient with the auxiliary (auxiliaries).These processes for the preparation of the compositions and the use ofthe compounds I for the preparation of these compositions are also asubject of the invention.

In another aspect the present invention provides a method of combatingand controlling pests which comprises treating the pests or the locus ofthe pests or the plant susceptible to attack by a pest with aninsecticidally, nematicidally or mollusicidally effective amount of acomposition according to this invention.

The application methods for the compositions, that is the methods ofcontrolling pests of the abovementioned type, such as spraying,atomizing, dusting, brushing on, dressing, scattering or pouring—whichare to be selected to suit the intended aims of the prevailingcircumstances—and the use of the compositions for controlling pests areother subjects of the invention. Typical rates of concentration arebetween 0.1 and 1000 ppm, preferably between 0.1 and 500 ppm, of activeingredient. The rate of application per hectare is generally 1 to 2000 gof active ingredient per hectare, in particular 10 to 1000 g/ha,preferably 10 to 600 g/ha.

A preferred method of application in the field of crop protection isapplication to the foliage of the plants (foliar application), it beingpossible to select frequency and rate of application to match the dangerof infestation with the pest in question. Alternatively, the activeingredient can reach the plants via the root system (systemic action),by drenching the locus of the plants with a liquid composition or byincorporating the active ingredient in solid form into the locus of theplants, for example into the soil, for example in the form of granules(soil application). In the case of paddy rice crops, such granules canbe metered into the flooded paddy-field.

The compositions according to the invention are also suitable for theprotection of plant propagation material, for example seeds, such asfruit, tubers or kernels, or nursery plants, against pests of theabovementioned type. The propagation material can be treated with thecompositions prior to planting, for example seed can be treated prior tosowing. Alternatively, the compositions can be applied to seed kernels(coating), either by soaking the kernels in a liquid composition or byapplying a layer of a solid composition. It is also possible to applythe compositions when the propagation material is planted to the site ofapplication, for example into the seed furrow during drilling. Thesetreatment methods for plant propagation material and the plantpropagation material thus treated are further subjects of the invention.

Further methods of application of the compositions according to theinvention comprise drip application onto the soil, dipping of parts ofplants such as roots bulbs or tubers, drenching the soil, as well assoil injection. These methods are known in the art.

In order to apply a composition according to the invention as aninsecticide, acaricide, nematicide, or molluscicide to a pest, a locusof pest, or to a plant susceptible to attack by a pest, a compound offormula I and, optionally, the plant growth regulator, are usuallyformulated into a composition which includes, in addition to thecompound of formula I and, optionally, the plant growth regulator, asuitable inert diluent or carrier and, optionally, a formulationadjuvant in form of a surface active agent (SFA) as described herein or,for example, in EP-B-1062217. SFAs are chemicals which are able tomodify the properties of an interface (for example, liquid/solid,liquid/air or liquid/liquid interfaces) by lowering the interfacialtension and thereby leading to changes in other properties (for exampledispersion, emulsification and wetting). It is preferred that allcompositions (both solid and liquid formulations) comprise, by weight,0.0001 to 95%, more preferably 1 to 85%, for example 5 to 60%, of acompound of formula I and, optionally, the plant growth regulator. Thecomposition is generally used for the control of pests such that acompound of formula I and, optionally, the plant growth regulator, isapplied at a rate of from 0.1 g to 10 kg per hectare, preferably from 1g to 6 kg per hectare, more preferably from 1 g to 1 kg per hectare.

When used in a seed dressing, a compound of formula I is used at a rateof 0.0001 g to 10 g (for example 0.001 g or 0.05 g), preferably 0.005 gto 10 g, more preferably 0.005 g to 4 g, per kilogram of seed.

The compositions can be chosen from a number of formulation types,including dustable powders (DP), soluble powders (SP), water solublegranules (SG), water dispersible granules (WG), wettable powders (WP),granules (GR) (slow or fast release), soluble concentrates (SL), oilmiscible liquids (OL), ultra low volume liquids (UL), emulsifiableconcentrates (EC), dispersible concentrates (DC), emulsions (both oil inwater (EW) and water in oil (EO)), micro-emulsions (ME), suspensionconcentrates (SC), oil-based suspension concentrate (OD), aerosols,fogging/smoke formulations, capsule suspensions (CS) and seed treatmentformulations. The formulation type chosen in any instance will dependupon the particular purpose en-visaged and the physical, chemical andbiological properties of the a compound of formula I and, optionally,the plant growth regulator.

Dustable powders (DP) may be prepared by mixing a compound of formula Iand, optionally, the plant growth regulator, with one or more soliddiluents (for example natural clays, kaolin, pyrophyllite, bentonite,alumina, montmorillonite, kieselguhr, chalk, diatomaceous earths,calcium phosphates, calcium and magnesium carbonates, sulphur, lime,flours, talc and other organic and inorganic solid carriers) andmechanically grinding the mixture to a fine powder.

Soluble powders (SP) may be prepared by mixing a compound of formula Iand, optionally, the plant growth regulator with one or morewater-soluble inorganic salts (such as sodium bicarbonate, sodiumcarbonate or magnesium sulphate) or one or more water-soluble organicsolids (such as a polysaccharide) and, optionally, one or more wettingagents, one or more dispersing agents or a mixture of said agents toimprove water dispersibility/solubility. The mixture is then ground to afine powder. Similar compositions may also be granulated to form watersoluble granules (SG).

Wettable powders (WP) may be prepared by mixing a compound of formula Iand, optionally, the plant growth regulator with one or more soliddiluents or carriers, one or more wetting agents and, preferably, one ormore dispersing agents and, optionally, one or more suspending agents tofacilitate the dispersion in liquids. The mixture is then ground to afine powder. Similar compositions may also be granulated to form waterdispersible granules (WG).

Granules (GR) may be formed either by granulating a mixture of acompound of formula I and, optionally, the plant growth regulator andone or more powdered solid diluents or carriers, or from pre-formedblank granules by absorbing a compound of formula I (or a solutionthereof, in a suitable agent) in a porous granular material (such aspumice, attapulgite clays, fuller's earth, kieselguhr, diatomaceousearths or ground corn cobs) or by adsorbing a compound of formula I (ora solution thereof, in a suitable agent) on to a hard core material(such as sands, silicates, mineral carbonates, sulphates or phosphates)and drying if necessary. Agents which are commonly used to aidabsorption or adsorption include solvents (such as aliphatic andaromatic petroleum solvents, alcohols, ethers, ketones and esters) andsticking agents (such as polyvinyl acetates, polyvinyl alcohols,dextrins, sugars and vegetable oils). One or more other additives mayalso be included in granules (for example an emulsifying agent, wettingagent or dispersing agent).

Dispersible Concentrates (DC) may be prepared by dissolving a compoundof formula I and, optionally, the plant growth regulator in water or anorganic solvent, such as a ketone, alcohol or glycol ether. Thesesolutions may contain a surface active agent (for example to improvewater dilution or prevent crystallisation in a spray tank).

Emulsifiable concentrates (EC) or oil-in-water emulsions (EW) may beprepared by dissolving a compound of formula I and, optionally, theplant growth regulator, in an organic solvent (optionally containing oneor more wetting agents, one or more emulsifying agents or a mixture ofsaid agents). Suitable organic solvents for use in ECs include aromatichydrocarbons (such as alkylbenzenes or alkylnaphthalenes, exemplified bySOLVESSO 100, SOLVESSO 150 and SOLVESSO 200; SOLVESSO is a RegisteredTrade Mark), ketones (such as cyclohexanone or methylcyclohexanone) andalcohols (such as benzyl alcohol, furfuryl alcohol or butanol),N-alkylpyrrolidones (such as N-methylpyrrolidone or N-octylpyrrolidone),dimethyl amides of fatty acids (such as C₈-C₁₀ fatty acid dimethylamide)and chlorinated hydrocarbons. An EC product may spontaneously emulsifyon addition to water, to produce an emulsion with sufficient stabilityto allow spray application through appropriate equipment. Preparation ofan EW involves obtaining a compound of formula I and, optionally, theplant growth regulator, either as a liquid (if it is not a liquid atroom temperature, it may be melted at a reasonable temperature,typically below 70° C.) or in solution (by dissolving it in anappropriate solvent) and then emulsifiying the resultant liquid orsolution into water containing one or more SFAs, under high shear, toproduce an emulsion. Suitable solvents for use in EWs include vegetableoils, chlorinated hydrocarbons (such as chlorobenzenes), aromaticsolvents (such as alkylbenzenes or alkylnaphthalenes) and otherappropriate organic solvents which have a low solubility in water.

Microemulsions (ME) may be prepared by mixing water with a blend of oneor more solvents with one or more SFAs, to produce spontaneously athermodynamically stable isotropic liquid formulation. A compound offormula I and, optionally, the plant growth regulator, is presentinitially in either the water or the solvent/SFA blend. Suitablesolvents for use in MEs include those hereinbefore described for use inin ECs or in EWs. An ME may be either an oil-in-water or a water-in-oilsystem (which system is present may be determined by conductivitymeasurements) and may be suitable for mixing water-soluble andoil-soluble pesticides in the same formulation. An ME is suitable fordilution into water, either remaining as a microemulsion or forming aconventional oil-in-water emulsion.

Suspension concentrates (SC) may comprise aqueous or non-aqueoussuspensions of finely divided insoluble solid particles of a compound offormula I and, optionally, the plant growth regulator. SCs may beprepared by ball or bead milling the solid compound of formula I in asuitable medium, optionally with one or more dispersing agents, toproduce a fine particle suspension of the compound. One or more wettingagents may be included in the composition and a suspending agent may beincluded to reduce the rate at which the particles settle.Alternatively, a compound of formula I and, optionally, the plant growthregulator, may be dry milled and added to water, containing agentshereinbefore described, to produce the desired end product.

Oil-based suspension concentrate (OD) may be prepared similarly bysuspending finely divided insoluble solid particles of a compound offormula I and, optionally, the plant growth regulator, in an organicfluid (for example at least one mineral oil or vegetable oil). ODs mayfurther comprise at least one penetration promoter (for example analcohol ethoxylate or a related compound), at least one non-ionicsurfactants and/or at least one anionic surfactant, and optionally atleast one additive from the group of emulsifiers, foam-inhibitingagents, preservatives, anti-oxidants, dyestuffs, and/or inert fillermaterials. An OD is intended and suitable for dilution with water beforeuse to produce a spray solution with sufficient stability to allow sprayapplication through appropriate equipment.

Aerosol formulations comprise a compound of formula I and plant growthregulator and a suitable propellant (for example n-butane). A compoundof formula I and plant growth regulator may also be dissolved ordispersed in a suitable medium (for example water or a water miscibleliquid, such as n-propanol) to provide compositions for use innon-pressurised, hand-actuated spray pumps.

A compound of formula I and plant growth regulator may be mixed in thedry state with a pyrotechnic mixture to form a composition suitable forgenerating, in an enclosed space, a smoke containing the compound.

Capsule suspensions (CS) may be prepared in a manner similar to thepreparation of EW formulations but with an additional polymerisationstage such that an aqueous dispersion of oil droplets is obtained, inwhich each oil droplet is encapsulated by a polymeric shell and containsa compound of formula I and, optionally, the plant growth regulator,and, optionally, a carrier or diluent therefor. The polymeric shell maybe produced by either an interfacial polycondensation reaction or by acoacervation procedure. The compositions may provide for controlledrelease of a compound of formula I and, optionally, the plant growthregulator, and they may be used for seed treatment. A compound offormula I and plant growth regulator may also be formulated in abiodegradable polymeric matrix to provide a slow, controlled release ofthe compound.

A compound of formula I and the plant growth regulator may also beformulated for use as a seed treatment, for example as a powdercomposition, including a powder for dry seed treatment (DS), a watersoluble powder (SS) or a water dispersible powder for slurry treatment(WS), or as a liquid composition, including a flowable concentrate (FS),a solution (LS) or a capsule suspension (CS). The preparations of DS,SS, WS, FS and LS compositions are very similar to those of,respectively, DP, SP, WP, SC, OD and DC compositions described above.Compositions for treating seed may include an agent for assisting theadhesion of the composition to the seed (for example a mineral oil or afilm-forming barrier).

A composition used according to the present invention may include one ormore additives to improve the biological performance of the composition(for example by improving wetting, retention or distribution onsurfaces; resistance to rain on treated surfaces; or uptake or mobilityof a compound of formula I and, optionally, the plant growth regulator).Such additives include surface active agents (SFAs), spray additivesbased on oils, for example certain mineral oils, vegetable oils ornatural plant oils (such as soy bean and rape seed oil), and blends ofthese with other bio-enhancing adjuvants (ingredients which may aid ormodify the action of a compound of formula I and, optionally, the plantgrowth regulator). Increasing the effect of a compound of formula I mayfor example be achieved by adding ammonium and/or phosphonium salts,and/or optionally at least one penetration promotor such as fattyalcohol alkoxylates (for example rape oil methyl ester) or vegetable oilesters.

Wetting agents, dispersing agents and emulsifying agents may be surfaceactive agents (SFAs) of the cationic, anionic, amphoteric or non-ionictype.

Suitable SFAs of the amphoteric type include betaines, propionates andglycinates.

Suitable SFAs of the non-ionic type include condensation products ofalkylene oxides, such as ethylene oxide, propylene oxide, butylene oxideor mixtures thereof, with fatty alcohols (such as oleyl alcohol or cetylalcohol) or with alkylphenols (such as octylphenol, nonylphenol oroctylcresol); partial esters derived from long chain fatty acids orhexitol anhydrides; condensation products of said partial esters withethylene oxide; block polymers (comprising ethylene oxide and propyleneoxide); alkanolamides; simple esters (for example fatty acidpolyethylene glycol esters); amine oxides (for example lauryl dimethylamine oxide); and lecithins.

Suitable suspending agents include hydrophilic colloids (such aspolysaccharides, polyvinylpyrrolidone or sodium carboxymethylcellulose)and swelling clays (such as bentonite or attapulgite).

The compound of formula I and the plant growth regulator may be appliedby any of the known means of applying pesticidal compounds. For example,it may be applied to the pests or to a locus of the pests (such as ahabitat of the pests, or a growing plant liable to infestation by thepests) or to any part of the plant, including the foliage, stems,branches or roots, to the seed before it is planted or to other media inwhich plants are growing or are to be planted (such as soil surroundingthe roots, the soil generally, paddy water or hydroponic culturesystems), directly or it may be sprayed on, dusted on, applied bydipping, applied as a cream or paste formulation, applied as a vapour orapplied through distribution or incorporation of a composition (such asa granular composition or a composition packed in a water-soluble bag)in soil or an aqueous environment.

The compound of formula I and the plant growth regulator may also beinjected into plants or sprayed onto vegetation using electrodynamicspraying techniques or other low volume methods, or applied by land oraerial irrigation systems.

Compositions for use as aqueous preparations (aqueous solutions ordispersions) are generally supplied in the form of a concentratecontaining a high proportion of the active ingredient, the concentratebeing added to water before use. These concentrates, which may includeDCs, SCs, ODs, ECs, EWs, MEs SGs, SPs, WPs, WGs and CSs, are oftenrequired to withstand storage for prolonged periods and, after suchstorage, to be capable of addition to water to form aqueous preparationswhich remain homogeneous for a sufficient time to enable them to beapplied by conventional spray equipment. Such aqueous preparations maycontain varying amounts of a compound of formula I (for example 0.0001to 10%, by weight) depending upon the purpose for which they are to beused.

A compound of formula I and the plant growth regulator may be used inmixtures with fertilisers (for example nitrogen-, potassium- orphosphorus-containing fertilisers, and more particularly ammoniumnitrate and/or urea fertilizers). Suitable formulation types includegranules of fertiliser. The mixtures suitably contain up to 25% byweight of the compound of formula I.

The invention therefore also provides a fertiliser compositioncomprising a fertiliser and a compound of formula I and, optionally, theplant growth regulator.

The compositions of this invention may contain other compounds havingbiological activity, for example micronutrients, saccharides, aminoacids, flavonoids, quinines; or other plant activators and/orstimulators and/or growth regulators like for example natural orsynthetic hormones, phytohormones such as auxins, brassinosteroids,gibberellins, polyamines, abscisic acid, cytokinins, jasmonates,cis-jasmonates, strigolactones, salicylic acid, ethylene,1-methylcyclopropene, or derivatives thereof; or compounds which possessfungicidal, herbicidal, safening, insecticidal, nematicidal oracaricidal activity.

Although it is believed that the present method can be applied to a seedin any physiological state, it is preferred that the seed be in asufficiently durable state that it incurs no damage during the treatmentprocess. Typically, the seed would be a seed that had been harvestedfrom the field; removed from the plant; and separated from any cob,stalk, outer husk, and surrounding pulp or other non-seed plantmaterial. The seed would preferably also be biologically stable to theextent that the treatment would cause no biological damage to the seed.It is believed that the treatment can be applied to the seed at any timebetween harvest of the seed and sowing of the seed or during the sowingprocess (seed directed applications). The seed may also be primed eitherbefore or after the treatment.

Even distribution of the compound and adherence thereof to the seeds isdesired during propagation material treatment. Treatment could vary froma thin film (dressing) of a formulation containing the compound, forexample, a mixture of active ingredient(s), on a plant propagationmaterial, such as a seed, where the original size and/or shape arerecognizable to an intermediary state (such as a coating) and then to athicker film (such as pelleting with many layers of different materials(such as carriers, for example, clays; different formulations, such asof other active ingredients; polymers; and colourants) where theoriginal shape and/or size of the seed is no longer recognisable intothe controlled release material or applied between layers of materials,or both.

The seed treatment occurs to an unsown seed, and the term “unsown seed”is meant to include seed at any period between the harvest of the seedand the sowing of the seed in the ground for the purpose of germinationand growth of the plant.

Treatment to an unsown seed is not meant to include those practices inwhich the active ingredient is applied to the soil but would include anyapplication practice that would target the seed during the plantingprocess.

Preferably, the treatment occurs before sowing of the seed so that thesown seed has been pre-treated with the compound. In particular, seedcoating or seed pelleting are preferred in the treatment of thecompound. As a result of the treatment, the compound is adhered on tothe seed and therefore available for pest control.

The treated seeds can be stored, handled, sowed and tilled in the samemanner as any other active ingredient treated seed.

According to the present invention, the plant growth regulator can beapplied alone or together with the compound of the formula I before orafter emergence of the plants. The treatment of the plants or the seedmaterial with the plant growth regulator can therefore take place inprinciple independently of the time of application of the compound ofthe formula I. The treatment of the plant by simultaneous application ofthe compound of the formula I and plant growth regulator (e.g. in theform of a tank mixture) is generally preferred.

The invention is illustrated by the following preparation examples. TheH-NMR data of certain compounds of this invention show line broadeningat room temperature, suggesting the existence of plural conformationalisomers due to, for example keto-enol tautomerism, hindered rotation,ring inversion in the piperidine moitey or nitrogen inversion at thepiperidine N—OR center. Broad signals have been labeled with ‘br’accordingly.

BIOLOGICAL EXAMPLES Example B1 Activity Against Rhopalosiphum padi(Cereal Aphid) and Crop Safety

The experiment was divided into two parts, one half of the plants wasused for the aphid bioassay the other half was not infested with aphidsand kept for plant growth evaluation. One replicate consisted of 4 wheatplants per pot. 5 replicates were infested with a mixed population ofcereal aphids 6 days after seeding. 9 days after seeding all wheatplants (10 replicates) were sprayed with respective test solutions. Testsolutions contained the formulated test compound (25 ppm), the adjuvantMero (0.1% v/v), and the plant growth regulator (PGR) CCC(chlormequat-chloride, Cyclocel®) or trinexapac ethyl (Moddus®). 6 and17d after application aphid mortality and phytotoxicity were evaluated.Efficacy was calculated with the aid of Abbott's formula. Assessment onphytotoxicity was done by counting the number of leaves bent down due tonecrosis per pot. Additionally the average plant height per replicatewas measured.

Tank mixing of PGRs with these insecticides clearly reduced thephytotoxicity of the test compounds. Test compounds caused 6DAA a morepronounced stunting effect on stem height than the commonly used PGRsfor this effect. 21DAA the plant growth is determined by the appliedPGR.

Example B2

Activity against Nilaparvata lugens (brown plant hopper, BPH) and cropsafety The experiment was divided into two parts, one half of the plantswas used for the plant hoppers bioassay the other half was not infestedwith insects and kept for plant growth evaluation. Eight replicates(pots with rice plants) were sprayed with respective test solutions.Test solutions contained the formulated test compound and the PGRModdus® at different ratios. 4 pots were infested with plant hoppernymphs right after application. 7d after application BPH mortality andphytotoxicity were evaluated. Efficacy was calculated with the aid ofAbbott's formula. Assessment on phytotoxicity was done by counting thenumber of leaves with chlorosis per pot.
